5 copper heatpipes and the MX-4 thermal compound (pre-applied) transfer heat from the GPU efficiently to the 35-fin heatsink and the two 92mm PWM fans create tremendous airflow to cool down the GPU temperature instantly, even when high performance is required during overclocking.

Funkykit tested the Accelero Twin Turbo II and showed that it reduced the GPU temperature on an HIS Radeon 7870 by up to 48 degrees.

Virtually Silent

The Accelero Twin Turbo II cools very efficiently with two ultra-quiet PWM fans. Tested by Hardware Secrets, it is by far the quietest cooler in the field.

Thanks to the PWM control, the speed of both fans adjusts according to the temperature of the GPU and thus the noise level remains at an absolute minimum. Click here to see how the PWM control settings can be changed according to your performance and noise preference.

Multi-compatibility

It features a versatile and interchangeable mounting system with 31 RAM and VR coolers in different sizes and shapes to accommodate a wide range of graphics cards. Its compatibility with CrossFire and SLI is perfect for multi-VGA setups.

New Fan Controller

An improved fan controller and the use of additional filters guarantee a smooth operation with both NVIDIA and AMD graphics cards. Through software, the temperature-fan speed curve can be adjusted. No matter whether you are a hardcore-gamer or a silent enthusiast, you get the temperature and noise level exactly where you want it to be.

* If your RTX board does not have a 4-pin fan header, you can contact ARCTIC Customer Support for a 14-pin adapter cable.

The compatibility list is based on AMD Radeon and NVIDIA's reference board layout only. Please check the height restriction drawing before purchase.

"Probably the best aftermarket cooler"

The Accelero Twin Turbo II is probably the best aftermarket cooler for mid-range card. It was able to have 28 degrees lower than the stock cooler during load while being virtually silent. The design looks really cool and the price tag is reasonable. We would like to give it the gold award.

Lovers of silence will appreciate this cooler. Accelero Twin Turbo II effortlessly cools the GPU, while emitting remarkably low noise. The cooler is efficient, silent and comes with a generous bundle, and deserves the Value award from Cowcotland.

Twin Turbo II provides everything a geek could want. Sensible cooling, solid bundle, both discrete and blistered appearance and a very reasonable price.

Finally, we can say that we got an outstanding good cooler below 30 Euros, which is able to cool power-hungry graphics cards such as the Radeon HD6970 in silent. A good and quiet cooler meets a quibble quality, an extensive package and a very high compatibility with current graphics cards. Therefore, I recommend the ARCTIC Twin Turbo II... [more]

The TT II has been upgraded by adding a heatpipe, and the fan has moved to the inside of the cooler. Cools effortless at low rpm's, which leads to quiter operation, and blows the reference cooler away.

TWIN TURBO II perfectly coped with its task, keeping the GPU temperature at 45C. Of course, the result has been achieved at the maximum fan speed, but the noise of the cooler at the same time so low, that even this mode is quite acceptable for everyday use.

Dropped the temperature by 13 degrees with ease during overclocking and lower rev. count. With the Accelero Twin Turbo II GTX 680 graphics card feels great - the core temperature is far from critical (and always lower than the reference), and the noise level is so low that I couldn't hear it even.

The Accelero Twin Turbo II is totally convincing in operation. Under the Windows Standard mode, the two fans work with low speed in total silence and was able to remain below 30 degrees. While overclocking the voltage and frequency, I brought the card to around 15% more power which is everything I wanted. It's cool man!

FAQ

Fan speed irregularities on Nvidia graphics cards

Nvidia graphics cards with their latest drivers may be misinterpreting the fan speed of our coolers and thus the reporting through software is wrong.
Further Nvidia is no longer controlling the fan speed depending on PWM values based on the GPU temperature. E.g. if you set 30% PWM, Nvidia translates it into 1050 RPM. Independent whether you run a 40 mm (10,000 RPM max) or a 140 mm (1,500 RPM max) fan and independent of their maximum fan speeds, Nvidia will drive both at exactly 1050 RPM.

Nvidia's inability interpreting the fan speed signal might make the graphics card's controller spin the fan up and down. AMD boards control the fan speed consequently according to the GPU temperature and thus this cannot happen.
With a fan controller software like MSI Afterburner this issue is controllable in the best way. There is to be aware that the percentages are not corresponding to PWM values but to fix fan speeds set by Nvidia. We recommend you to follow our suggested control curve precisely.

Compatibility with AMD R9 285, 280(X), 7970 and 7950

The Accelero Twin Turbo II is compatible to the above mentioned boards if the GPU was manufactured after February 2013. Please put a ruler on top of the GPU and check whether there is a gap between the ruler and the GPU. If there is a gap, the GPU was manufactured before February 2013. In this case please use the Accelero Xtreme IV-280(X).

How to use the 4-pin adapter?

Under what conditions do you need a 4-pin adapter?

Your graphics card

1. is using a non-standard cooler socket (e.g. 5-pin, flipped polarity) or
2. is using a passive cooler as the stock cooler

How to connect the 4-pin adapter?

The differences between 7V and 12V socket*

7V: Moderate fan speed. It gives the best balance between cooling performance and noise level. It is recommended for normal usage.
12V: Full fan speed depending on the fan design. It gives the best cooling performance and it is recommended for high duty usage.

*The fan speed is fixed regardless of the GPU's condition.

Steps

1. Ensure your PSU has spare power source and plug in the 4-pin adapter.

Please note: Make sure the connector is plugged into the corresponding socket (i.e. A 3-pin plug should be connected to a 3-pin socket and a 4-pin plug should be connected to a 4-pin socket). If the plug is connected to the wrong socket, the motor will burn immediately due to incorrect polarity.
